In the case of lights with different emitters, because they perform very differently but the owners probably like all the other aspects of those lights.
Other people get them in different colors, metals, etc. which I don’t get but that kind of “collector” mindset is common for lots of hobbies.
Don’t want to think of all the possibilities, which LED will the SF11
Take.
It’s a simple matter of desoldering the two leads, and resoldering the new
On once one get the proper LED. The person used two Phillip screws to anchor the Led plate.
The two screws are a bit lopsided. A hack job, I guess….
And the LED became detached….
Would appreciate the part #, if someone is in the know.
Mass is Massachusetts, USA? I would order from MTN. The SF11 comes with an XPL stock. You can choose your color, CW, NW, etc… You just need to find the diameter, like 16mm, 22mm, etc…
The screws are probably factory, they are there to keep the MCPCB from rotating.
While its entirely possible , likely even that other life exists out there, it is also equally possible we really are the only ones , so not naive sadly
I disagree. Once people understand just how vast space is, our nearest star is like 4 something light years away, and you factor in that Earth has only been transmitting signals about 100 years, you realize those signals have only reached a handful of nearby stars. I’m pretty sure life is out there, but they not only need to be within this super short distance to even know we exist, but also in this tiny sweet spot of time in their civilization where they are intelligent, but not nuked themselves back to the stone age yet. This might be a few 100 years within hundreds of millions of years. So if this super rare synchronization happens, they still need to have faster than light travel just to get here. So the odds of any two civilizations actually meeting are much, much lower than there being multiple civilizations out there. More than likely we would be the aliens finding “life” out there in the form of bacteria or maybe animals.
To sum it up, odds are quite good for life out there. There could be millions of planets with life and some of which are complex and maybe intelligent.
The odds of us or any of them coming into contact, almost non existant. The distances are just too far.
Star Trek is cool in that it looks like we could find other groups, but the reality is that even at just under Warp 10, about 6000 times the speed of light, the Enterprise would take years to travel the super long distances, even decades or centuries. This would not make good television, so they have to shorten the distances and times dramatically. We can’t even travel within a fraction of Warp 1, speed of light, much less many times faster. Practically speaking, we’d need to go much, much faster than these Warp drives. Space is seriously way bigger than we can wrap our heads around. (All my opinion)
While I am fully familiar with the drake equation and the Fermi paradox , the fact remains it’s only a theory to make an assumption without evidence and draw a conclusion is not scientific, it is equally possible we are such an extreme fluke we are the only ones in the entire universe , sadly neither theory is proven , there is no right or wrong answer here we simply have to acknowledge both possibilities and remain neutral until evidence exists.
Radio signals travel way too slow, speed of light, to really go very far. Plus SETI is so new. Our early 20th century transmissions have gone much, much further. If we limit ourselves to there being intelligent life in our own galaxy, it could take 100,000 years for the signals to reach them and the same time for them to respond. We’d be gone and buried.
Maybe we will figure out communication like in Star Trek where it is through “sub space” and almost instantaneous. This would make things interesting. A bunch of aliens all talking on this shared “party line”. Travel would still be impossible, but maybe we will figure out how to make space/time our b!tch and just blink from one side of the universe to the other. Ah, sci-fi is cool.
